is it possible to overwrite a error or success message generated by the magento?

Is it possible to overwrite a erro开发者_运维知识库r/success message generated by the magento system?

For example if we add a product the success message is "Laptop is added to your cart..!", what if i would like to add my client's name like "Josh you had added Laptop to your cart"

Thanks, Balan

It's easy enough to add your custom message to the stack when an item is added. Add an event listener for checkout_cart_add_product_complete which does this:

public function observeAddToCart($observer) { 
    $product = $observer->getEvent()->getProduct(); // you may need to play with this
    $session = Mage::getSingleton("checkout/session")->addSuccess($message); 
    $message = Mage::helper("yourmodule")->__('%s, you added %s to your shopping cart.', Mage::helper('core')->htmlEscape($product->getName()));
    $session->addSuccess($message); 
}

That leaves the problem of removing the old message. The closest that I see right now is that you can clear all other messages on command by retrieving them. So you could clear the Magento-set message afterwards like so:

Mage::getSingleton("checkout/session")->getMessages(true);

You would need to do this after Magento's message has been added, however. Hope that gives you a start!

I've written a helper function that allows you to search for a specific message with an option to remove if found. It's a bit disappointing this isn't available in core..

/**
 * Searches messages for @param $string.
 * Will remove the message if $remove is true.
 *
 * @param string $string
 * @param boolean $remove: false
 * @param string $which: core/session
 * @return true|false, found|not found
 * @access public
 */
public function message_search( $string, $remove = false, $which = 'core/session' ) {

  $found = false;

  $messages = Mage::getSingleton( $which )->getMessages();
  foreach( $messages->getItems() as $message )
    if( stristr( $message->getText(), $string ) ) {
      $found = true;
      if( $remove ) $message->setIdentifier( 'this_message_will_be_removed' );
    }

  if( $remove ) $messages->deleteMessageByIdentifier( 'this_message_will_be_removed' );
  return $found;

}
